monoatomic ideal gas ( = 5=3, cV = 3R=2), initially at a vol- ume V1 and temperature T1 = 298 K, by increasing its pressure from P1 = 101:3 kPa to P2 = 500 kPa. From step 2 to 3, the pressure increases from P2 = 500 kPa to P3 = 1500 kPa. From step 3 to 4, the pressure decreases from P3 = 1500 kPa to P4 = 600 kPa and T4 = 550 K. What is the total amount of work w done by the cycle?

Which of these describe conduction transfer of heat between two objects that are touching transfer of heat by the actual movement of war matter the process in which energy is imitated by one of the object transmitted through space and absorbed by another a process in which energy is released by the molecules breaking apart

Ablock of mass m = 2.5 kg is attached to a spring with spring constant k = 710 n/m. it is initially at rest on an inclined plane that is at an angle of θ = 23° with respect to the horizontal, and the coefficient of kinetic friction between the block and the plane is μk = 0.19. in the initial position, where the spring is compressed by a distance of d = 0.16 m, the mass is at its lowest position and the spring is compressed the maximum amount. take the initial gravitational energy of the block as zero. a) what is the block's initial mechanical energy? b) if the spring pushes the block up the incline, what distance, l, in meters will the block travel before coming to rest? the spring remains attached to both the block and the fixed wall throughout its motion.

Within a pendulum, as potential energy decreases, energy increases. a. heat b. kinetic c. frictional d. gravitational
